II. START-UP MINIBUMP SOURCE
To start the generator,
press and hold
the ON/OFF Switch, located in the
middle front of the instrument, until the GREEN LED turns on, approximately
3 seconds
. Release the switch immediately thereafter.
The GREEN LED will blink at a rapid rate indicating the number of hours
of gas remaining in the source (5 blinks indicates 5 hours of life
remaining). It will then blink at a rate of once a second for approximately
20 seconds. Gas will begin to be generated immediately. After 20
seconds, the green light will stay illuminated and the pump will begin
running. With a bump source installed, the unit will run for an additional
20 seconds providing a ‘bump’ of output gas to drive the connected
sensor into alarm after which both red and green lights will alternate
indicating that the instrument is purging. It will shut off automatically
after an additional 25 seconds. Note: Some sensors have faster
response times than others. If the system does not respond to the gas
within 30 seconds, continue to leave the MiniBump attached to the sensor
throughout the purge cycle and if needed, run the bump cycle a second
time.
If the RED LED begins flashing or remains lit continuously it indicates the
instrument is in either low battery condition or source failure mode.
